It has ~366 records of Livingston, 600-some of Livingstone, no MacLea or McLea or anything similar, unless I am not searching correctly.

I didn't really look through all of those hundreds of records, so it is possible that they are of genealogical interest... but of course before the name change, we seem to have mostly records of the lowland Livingston family and also the Livingstones seem to be of groups I'm not familiar with...
